Our round galvanized elbows are available in both plain round (smooth round), and round corrugated.
Plain Round Elbows are available in 3" and 4" diameters. Round Corrugated Elbows are available in 3", 4", 5" and 6" diameters.
Galvanized elbows can be soldered, riveted, or screwed to the adjoining downspouts.
More info: Flat seam design can occur due to stretching of diameter when forming. This can permit capillary action to cause drips from seam when used in lower position with water flow on seam. This may require sealant or solder to prevent drip.
